摘要： A forged crankshaft includes a plurality of main journals, a plurality of crank pin journals rotatable in a circular path about axes defined by the main journals, and a plurality of crank webs. At least one crank web of the plurality of crank webs defines a middle crank web which is located between and connects two neighboring crank pin journals of the plurality of crank pin journals. The middle crank web has a stress relief forged therein, which is defined by first and second spaced sidewalls, an inner wall and a base wall. The forged-in stress relief has a predetermined depth, wrap angle, radius, and undercut which together define a shape of the forged-in stress relief. The shape of the forged-in stress relief is controlled to reduce stress in the crankshaft.

摘要： An engine timing plate is disclosed that is generally positioned between a crankshaft surface and a main journal. The engine timing plate is not bolted or otherwise secured to either the crankshaft surface or the main journal. Instead, the timing plate “floats” between the two surfaces. The timing plate includes protruding portion that mates or temporarily associates with a receiving portion disposed on the crankshaft. The timing plate also generally includes a raised surface forming an integrated thrust surface that may engage with, but not necessarily interlock with, one or both of the crankshaft surface and the main journal. Thus, the rotational motion of the crankshaft maintains the relative position of the timing plate with respect to the crankshaft surface and/or the main journal without the use of standard mechanical connectors, such as bolts.

摘要翻译： 公开了通常位于曲轴表面和主轴颈之间的发动机正时板。 发动机正时板没有螺栓连接或以其他方式固定到曲轴表面或主轴颈上。 相反，定时板在两个表面之间“浮动”。 定时板包括与设置在曲轴上的接收部分配合或临时关联的突出部分。 正时板还通常包括形成整体推力表面的凸起表面，其可以与曲轴表面和主轴颈中的一个或两个接合但不一定互锁。 因此，曲轴的旋转运动保持正时板相对于曲轴表面和/或主轴颈的相对位置，而不使用诸如螺栓的标准机械连接器。
